Answer:
Each axis needs a scale to show the range of the data on that axis. The low end of the scale may be zero or a round number value slightly smaller than the smallest data point. The high end of the scale is usually a round number value slightly larger than the largest data point. The scale is measured off in major and minor tick marks. Typically the scale runs from low to high in easily counted multiples like 10s, 50s, 100s, etc. When graphs are compared side-by-side, consider scaling them to the same data range to make comparisons easier.

Answer:
Ashing process is done to evaluate the ash content present in petroleum or other proucts, so that they can be used for certain applications
The two major types of ashing process that includes dry ashing and wet ashing and can be performed using microwave systems or conventional means.
a. errors made in the preceding method while determining the ash content of buttermilk by conventional dry ashing are as following:
- Buttermilk should not immediatly put into muffle immediatley, it should be boiled first to avoid splatter.
- Temperature should be between 500 to 600 degree celcius at high temperature teh ash content can be loss.
- The sample should be ashed for 12-18 hrs
, more than this can damage the required ash content.
- platinum tip should be used in place of stainless steel because platinum has a lower concomitant tip impedance than stainless stell, so less reactive to ash.
- The ash should put in dessicator and not allow to kept in open because ash can react with the humidity in teh atmosphere.
b. The result that occur due to above errors such as the temperature, time, tongs and leaving ash in open will manipulate the final ash content and its application can be harmful for humans and for other purpose if it will be used.
